hey all.
LG WM0642HW approx 8 years old, but still in great shape until last month. Heavy grinding noise. Took of the back off and ran a cycle to watch it. The motor rotor bolt (part AP4436414) became really loose during the wash and rinse cycle when the drum was turning counter-clockwise (watching from the back). So much that I had to manually keep it on.

I ordered a new motor rotor bolt, tightened it as much as i could with loc-tite and a wrench.

Now it is a bit better. Sometimes sticks in the wash cycle, usually sticks during rinse cycle, but isn't as noisy. Totally fine during the spin cycle. See video link: https://youtu.be/4cD8A9Wuy2Q

Any thoughts? Not tight enough? Or something else happening that I need to look at?
